CORN-SHELLER.

SPECIFICATION forming part of Letters Patent No. 736,615, dated August18, 1903.

Application filed November 21,1902. Serial No. 132,750. (No model.)

To all whom it may concern.-

Be it known that I, ALEXIS R. MONTGOM- ERY, of the city of Decatur,county of Macon, and State of Illinois, have invented certain new anduseful Improvements in Corn-Shellers, of which the followingis aspecification.

This invention provides simple and effective means for shelling corn inthe throats of shellers while forcing the corn into the shelling-spacebetween the concave and the cone or cylinder.

The invention is exemplified in the structure hereinafter described, andit is defined in the appended claims.

A corn-sheller of the advanced type comprises an externally-toothed conemounted on a horizontal shaft and incased by an internally toothedconcave. An opening is made in the sheller-casing at the small end ofthe cone to receive the corn, an appliance is placed on the shaft in thethroat of the cylinder to force the corn into the space between the coneand the concave, and it is desirable for several reasons that thefeeding appliance shall shell a large per cent. of the corn. Oneadvantage in shelling corn in the throat of the sheller by means of thefeeding appliance is based on the general principle that it ismechanical economy to get all the work possible with a given expenditureof force, and specific advantages are as follows: The under part of thethroat of the casing is composed of a set of bars or rods separated togive a large degree of freedom for the passage of shelled corn, cobs andhusks do not pass between the rods to any detrimental extent, and thatpart of the separating-sieve under the throat of the shellerisparticularly. free from obstructions and well capable of taking care ofa large quantity of shelled corn. Nhen there is but little shelling inthe throat of the sheller, the unshelled corn passes into the spacebetween the cone and the concave, much of the corn shelled thereinpasses through the sheller with the oobs and husks, and the masssmothers the sieve to an extent that some of the grains are unable tofind a way through the sieve and are carried 0% with the husks-or cobs.

I-Ieretofore the throats of shellers have been supplied with continuousspiral feeders in some instances which have fed the corn into thesheller quite effectively without producing much result so far asshelling is concerned, and in other instances non-feeding beaters havebeen used, with the result that shelling in the throat has beenaccomplished at the expense of a curtailment of the general efficiencyof the sheller through slowness of feed.

My invention is designed to provide means for feeding the corn into thesheller proper as fast as a proper amount of shelling in the throat willpermit and to shell as much in the throat as is consistent with a properdegree of speed in the feeding. To accomplish this result, I make a setof collars adapted to fit on the sheller-shaft, extend an obliquefeeding-blade from one side of each collar, and extend a non-feedingbeater from the opposite side of the collar. The set of collars arefastened onto the shaft with the feeder-blades each presented in adifferent direction in a break-joint or non-coincident manner, and whencorn is supplied to the throat of the sheller and the sheller-shaft isturned in the proper direction the feeder-blades will advance the corntoward the sheller, while the beaters coact with the rods of the casingto shell the corn, and the full capacity of the sheller is attainedwithout overtaxing the sieves.

In the drawings forming part of this specification, Figure 1 is arepresentation, partly in side elevation and partly in vertical section,of so much of a sheller as is needed to explain my invention. Fig. 2 isan end View of a set of combined feeders and shellers properly arrangedon the sheller-shaft. Fig. 3 is a diagram of one of the combinedshellers and feeders.

The throat of the sheller is shown at 1 in Fig. 1, and the rods thatform the lower part of the throat-casing are shown at 2. Thesheller-shaft is designated by reference-numeral 3. The cone of thesheller, commonly called the cylinder, is shown at 4, and the concave ofthe sheller is shown at 5. The collars for the combined feeders andbeaters are shown at 6. The feeder-blades are shown at 7, and thesheller-beaters are shown at 8.

The number of combined feeders and beaters may be varied to meet variousrequirements, the degree of obliquity of the feederblades may be made tosuit different conditions, and the general shape and proportion of thedifierent features may be altered without departing from the principleof my invention. The gist of the invention is present in any embodimentin which feedingblades are alternated or intermingled with non-feedingsheller-blades on the shaft in the throat of the sheller.

I claim 1. A combined feeder and sheller for the throats ofcorn-shellers; comprising a set of collars fastened onto thesheller-shaft in the throat of the sheller, each collar having anoblique feeding-blade extending in one direc-
